Sıralı Küme Örneklemesi, ilgili
değişken bakımından örnekleme birimlerini ölçmenin maliyet veya zaman
bakımından zor olduğu durumlarda Basit Tesadüfi Örnekleme’ye göre daha etkin
bir örnekleme yöntemidir. Güven aralığı ve hipotez testi gibi istatistiksel
çıkarımlar yapılırken dağılım varsayımına ihtiyaç duyulur. Dağılım bilgisinin
olmadığı veya istatistiksel çıkarımın mümkün olmadığı durumlarda ise yeniden
örnekleme teknikleri kullanılabilir. Bootstrap yöntemi de bunlardan biridir. Bu
çalışmada, Sıralı Küme Örneklemesinde yığın ortalamasına ilişkin güven aralığı
üç farklı bootstrap yöntemi kullanılarak ele alınmıştır. Bu yöntemler
kullanılarak güven aralığı kapsama olasılıkları ve güven aralığı genişlikleri
farklı dağılımlar kullanılarak simülasyon yoluyla elde edilmiştir. Simetrik
olmayan dağılımlara göre simetrik dağılımlar için elde edilen güven aralığı
kapsama olasılıklarının belirlenen güvenilirlik düzeyine daha yakın sonuçlar
verdiği görülmüştür.

Ranked Set Sampling is a more effective
sampling method than Simple Random Sampling when it is difficult to measure
sampling units in terms of cost or time. When statistical inferences such as
confidence interval and hypothesis testing are performed, distributional
assumption is required. Resampling techniques can be used when there is no
distributional information or it is imposible to make statistical inference.
The bootstrap method is one of these techniques. In this study, the confidence
interval for the population mean in Ranked Set Sampling are considered by using
three different bootstrap techniques. By using these methods, confidence interval
coverage probabilities and confidence interval widths are obtained by
simulation using different distributions. It is observed that confidence
interval coverage probabilities under symmetrical distributions are closer to
the nominal level than confidence interval coverage probabilities under
nonsymmetrical distributions..
